// Pure geometry math for GeckoLib/Blockbench geo.json models.
// No Three.js dependency — shared by model_viewer.js (browser) and unit tests (Node).
//
// Transforms follow the GeckoLib convention: each bone contributes
// local = T(pivot) · R(bone.rotation) · T(pivot)
// and cubes are authored in model space (origin at feet, Y up).
// `build()` flattens the bone tree into world-space cubes, avoiding the
// nested-pivot double-counting that broke naive group-based renderers.
